... Consequently, space payloads fall into weight classes that generally span the performance bands of these systems. Since there are no firm plans that are not satisfied by the performance of existing launch systems, the prospective launch system and propulsion system developer must rely on speculative projections of potential future users as opposed to firm plans and requirements to define the performance .

... The Committee also observed that a new trend toward less expensive, lightweight satellites operating in LEO, which support civil cellular communications, tactical military communications, and other defense applications, could produce additional traffic in the 2,000pound-or-less payload class during this intermediate period. Currently, a fledgling, venture

... may specify heavier lift requirements for space launch in the 135,000- to 600,000-pound to LEO range. In addition, routine support of SSF during its continuously manned operational phase may require as many as six service missions per year, including two or three missions that transfer personnel in a man-rated launch vehicle.
